摘要： A color liquid-crystal display panel has a red filter segment in each red sub-pixel and a blue filter segment in each blue sub-pixel, but no green filter segment in green sub-pixels. The liquid-crystal display panel has a backlight source for illuminating, and the backlight source has green light producing components alternately switched on and off in consecutive frames. The backlight source also has white or red/blue, or purple light emitting components alternately switched on and off in consecutive frames in complementary phase to the green light producing components. When the liquid crystal layer segments associated with all the three color sub-pixels are operated in a light non-blocking state, only the white or red/blue light producing components are turned on, and when the liquid crystal layer segments associated with the red sub-pixels are operated in a light blocking state, only the green light producing components are turned on.

摘要： When temperature variation occurs to the LED dice of an LED lighting system, a feedback control mechanism is applied to compensate temperature-related wavelength shift for precisely controlling the light generated by the LED dice based on the voltage drop variation or current variation of the LED dice. The color control method for the LED lighting system includes a preliminary detection phase and a feedback control phase. In the preliminary detection phase, voltage drop signals or current signals together with corresponding color and hue signals of each LED module of the LED lighting system are detected. In the feedback control phase, signal compensating processes are performed to precisely control the light generated by the LED lighting system based on the voltage drop variation or the current variation in conjunction with the corresponding color and hue signals generated in the preliminary detection phase.
